Israel's development of nuclear weapons owed a lot to France, Germany and the US. From here: https://www.theguardian.com/world/2014/jan/15/truth-israels-secret-nuclear-arsenal https://www.theguardian.com/world/2014/jan/15/truth-israels-... "In Dimona, French engineers poured in to help build Israel a nuclear reactor and a far more secret reprocessing plant capable of separating plutonium from spent reactor fuel. This was the real giveaway that Israel's nuclear programme was aimed at producing weapons. By the end of the 50s, there were 2,500 French citizens living in Dimona, transforming it from a village to a cosmopolitan town, complete with French lycées and streets full of Renaults, and yet the whole endeavour was conducted under a thick veil of secrecy. The American investigative journalist Seymour Hersh wrote in his book The Samson Option: "French workers at Dimona were forbidden to write directly to relatives and friends in France and elsewhere, but sent mail to a phony post-office box in Latin America." Seymour Hersh's book 'The Sampson Option' goes into more detail.
